[0034] The embodiments and terminology used in this document are not intended to limit the technical features described in this document to a specific embodiment, but should be understood to encompass various modifications, equivalents, or alternatives of the embodiment. In connection with the description of the drawings, similar reference numerals may be used to refer to similar or related components. The singular form of a noun corresponding to an item may include one or more of the item, unless the context clearly indicates otherwise.

[0035] In this document, the phrases "A or B", "at least one of A and B", "at least one of A or B", "A, B, or C", "at least one of A, B, and C", and "at least one of A, B, or C" can each include any one of the items listed together in that phrase, or all possible combinations thereof.

[0036] In this document, when a component (e.g., a first component) is referred to as being “connected,” “coupled,” or “connected,” with or without the terms “functionally” or “communicatively,” or “coupled” or “connected,” it means that the component can be connected to the other component directly (e.g., wired or wirelessly), or indirectly (e.g., via a third component).

[0037] The methods according to various embodiments disclosed in this document may be provided as a computer program product. The computer program product may be traded as a commodity between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read-only memory, CD-ROM), or may be distributed online (e.g., downloaded or uploaded) through an application store or directly between two user devices. In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily generated in a machine-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or an intermediary server.

[0038] According to the embodiments disclosed in this document, each component (e.g., a module or a program) of the above-described components may include one or more entities, and some of the entities may be separated and placed in other components. According to the embodiments disclosed in this document, one or more components or operations of the aforementioned components may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., a module or a program) may be integrated into a single component. In this case, the integrated component may perform one or more functions of each of the plurality of components identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to the embodiments disclosed in this document, the operations performed by a module, program, or other component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.

[0039] FIG. 1 illustrates a data collection system in a manufacturing process of a battery cell according to some embodiments.

[0040] Referring to FIG. 1, the data collection system (100) can collect inspection data used for inspection of a battery cell (110) in the manufacturing process of the battery cell (110) into a database (130).

[0041] The battery cell (110) may include a cylindrical battery cell. The battery cell (110) may be manufactured through detailed manufacturing processes. To determine whether each detailed manufacturing process has been performed normally, the data management system (120) may generate inspection data. The database (130) may record the inspection data.

[0042] When inspection data is generated and managed during the manufacturing process of a battery cell (110), excessive data transmission traffic can cause some data to be lost. For example, when inspection images and values ​​are generated for multiple battery cells, high-capacity images can be transmitted to a single intermediate management device in a short period of time. In this case, communication capacity may exceed its limits, resulting in some data loss.

[0043] To solve this problem, the data management system (120) can prevent excessive data traffic from occurring by applying different communication methods for each type of data collection device and each type of data being collected, and thus prevent some of the inspection data from being omitted.

[0044] FIG. 2 illustrates elements constituting a data management system according to some embodiments.

[0045] Referring to FIG. 2, the data management system (120) may include a first inspection device (121), a second inspection device (122), a collation device (123), and a management server (124). However, the present invention is not limited thereto, and some components may be omitted from the data management system (120), or other general-purpose components may be further included in the data management system (120).

[0046] The first inspection device (121) and the second inspection device (122) can collect inspection data to determine whether the detailed manufacturing processes of the battery cell (110) have been properly performed. The inspection data may include image data capturing the process results of each detailed manufacturing process. To this end, the first inspection device (121) and the second inspection device (122) may include a photographing means such as a camera or an image sensor.

[0047] According to an embodiment, detailed manufacturing processes of a battery cell (110) may include a process for manufacturing a battery electrode assembly, a process for sealing the electrode assembly within a battery can, etc. The first inspection device (121) and the second inspection device (122) may photograph the electrode assembly, the battery can, etc. as process results.

[0048] According to an embodiment, the first inspection device (121) may include one of a standalone vision inspector and a PC vision inspector, and the second inspection device (122) may include the other of the standalone vision inspector and the PC vision inspector. The standalone vision inspector may include its own separate controller, through which it may independently perform image capture and data transmission, etc. The PC vision inspector may process inspection data based on a PC. The first inspection device (121) and the second inspection device (122) may communicate with the collation device (123) through a wired or wireless communication network.

[0049] The collating device (123) may include a PC device and may have a general-purpose memory and processor. The collating device (123) may receive inspection data from the first inspection device (121) and the second inspection device (122). According to an embodiment, the collating device (123) may execute intermediate management software for managing the inspection data transmitted from the first inspection device (121) and the second inspection device (122). For example, the collating device (123) may convert the data format of some of the inspection data. The collating device (123) may collate the inspection data transmitted from the first inspection device (121) and the second inspection device (122) and provide the same to the management server (124).

[0050] The management server (124) can record and manage the collation data provided from the collation device (123). The management server (124) can store the inspection data in a database. According to an embodiment, the inspection data transmitted from the first inspection device (121) and the second inspection device (122) can include image data and value data, and the management server (124) can separately manage the image data and value data using different DBs.

[0051] The first inspection device (121) may be configured to generate a first inspection image and first inspection values ​​for the result of the first manufacturing process of the battery cell (110). For example, the first inspection device (121) may capture the result of any one of the detailed manufacturing processes of the battery cell (110) to generate the first inspection image, and may derive the first inspection values ​​through image processing on the first inspection image.

[0052] The second inspection device (122) may be configured to generate a second inspection image and second inspection values ​​for the result of the second manufacturing process of the battery cell (110). For example, the second inspection device (122) may capture the result of any one of the detailed manufacturing processes of the battery cell (110) to generate the second inspection image, and may derive the second inspection values ​​through image processing on the second inspection image.

[0053] The collating device (123) may be configured to receive the first inspection image, the first inspection values, the second inspection image, and the second inspection values ​​using a plurality of communication methods. In an embodiment, the communication method used by the collating device (123) to receive inspection data from the first inspection device (121) may be different from the communication method used by the collating device (123) to receive inspection data from the second inspection device (122). In an embodiment, the communication method used by the collating device (123) to receive the inspection image may be different from the communication method used by the collating device (123) to receive the inspection values. In this manner, a situation in which some data is lost due to traffic overload during the process of collecting inspection data can be prevented.

[0054] The management server (124) may be configured to record the first inspection image and the second inspection image in a first database, and record the first inspection values ​​and the second inspection values ​​in a second database. Since the inspection images and inspection values ​​are managed in separate databases, more efficient data management can be performed. According to an embodiment, the management server (124) may determine whether the battery cell (110) is defective based on the first inspection values ​​and the second inspection values, and may determine in which detailed process the defect occurred.

[0055] According to an embodiment, the plurality of communication methods may include a first communication method for receiving the first test values, a second communication method for receiving the first test image, and a third communication method for receiving the second test image and the second test values. The first test device (121) may transmit the first test values ​​and the first test image to the collating device (123) using two different communication methods. The second test device (122) may transmit the second test image and the second test values ​​to the collating device (123) in a different communication method from the communication method of the first test device (121) to avoid traffic overload.

[0056] According to an embodiment, the first communication method may include a TCP / IP communication method, the second communication method may include an FTP communication method, and the third communication method may include an SMB communication method. The TCP / IP (Transmission Control Protocol / Internet Protocol) communication method can specify detailed rules for communication standards between computers and for routing and interconnection of networks. TCP / IP can be utilized for communication of image data, but the transmission of a large amount of image data can cause traffic overload. FTP (File Transfer Protocol) can refer to a communication protocol for exchanging data between electronic devices. The inspection value can be transmitted using the FTP communication method. SMB (Server Message Block) can refer to a protocol developed to allow a Windows system to share resources such as disks or printers of other systems. To prevent data loss due to traffic overload, the third communication method can be set to an SMB method instead of TCP / IP or FTP.

[0057] According to an embodiment, the first inspection device (121) may be configured to analyze a first inspection image to extract first inspection values ​​having a first data format, and the second inspection device (122) may be configured to analyze a second inspection image to extract second inspection values ​​having a second data format, wherein the second data format may have a larger capacity than that of the first data format and a higher readability than that of the first data format. According to an embodiment, the second inspection device (122) may have a higher processing performance than the first inspection device (121), and the SMB communication method may have a higher communication performance than the TCP / IP communication method. By utilizing these points, the second data format transmitted by the second inspection device (122) via the SMB communication method may have a higher capacity and readability than the first data format.

[0058] According to an embodiment, the first data format may include a CSV format, and the second data format may include a JSON format. The CSV (Comma Separated Values) format may be a low-capacity format that simply separates data content. The JSON (JavaScript Object Notation) format is a character-based standard format for expressing data structured with JavaScript object grammar, and may have relatively high identification ability and readability. By distinguishing the formats of the inspection data provided by the first inspection device (121) and the second inspection device (122) into the CSV format and the JSON format, more efficient traffic management can be performed.

[0059] According to an embodiment, the collating device (123) may be configured to convert the data format of the first inspection values ​​from the first data format to a second data format, and transmit the second inspection values ​​and the first inspection values ​​converted into the second data format to the management server (124). Inspection data management in the management server (124) may require unification of the data format. Since the first inspection device (121) and the second inspection device (122) use different data formats for data traffic management, the collating device (123) may unify the data format. Through this structure, data traffic overload can be avoided while also allowing data management in the management server (124) to proceed smoothly.

[0060] According to an embodiment, the battery cell (110) may include a cylindrical battery cell, and one of the first manufacturing process and the second manufacturing process may include a process of forming an electrode assembly of the cylindrical battery cell, and the other of the first manufacturing process and the second manufacturing process may include a process of sealing the cylindrical electrode assembly in a cylindrical can to form the cylindrical battery cell. According to an embodiment, the detailed processes of the cylindrical battery cell may further include a positive electrode forming process, a negative electrode forming process, a separator forming process, a lamination process, a stacking process, a winding process, etc. In this case, additional inspection devices may be provided in addition to the first inspection device (121) and the second inspection device (122).

[0061] In an embodiment, the first inspection image may include an image of one of the electrode assembly and the cylindrical can, the second inspection image may include an image of the other of the electrode assembly and the cylindrical can, the first inspection values ​​may include dimensional values ​​of the electrode assembly, and the second inspection values ​​may include dimensional values ​​of the cylindrical can. For example, if the detailed dimensions of the electrode assembly and / or the cylindrical can are outside a predetermined normal range, this may be determined as defective. In an embodiment, the management server (124) may apply a statistical technique to the first inspection values ​​and the second inspection values ​​to determine whether the electrode assembly and / or the cylindrical can is defective.

[0062] Figure 3 illustrates a data management method in a battery cell manufacturing process according to the prior art.

[0063] Referring to FIG. 3, a conventional structure (300) for managing inspection data in a manufacturing process of a battery cell (110) can be illustrated.

[0064] In the conventional structure (300), both the standalone vision inspector (310) and the PC vision inspector (320) can utilize TCP / IP communication and FTP communication. Specifically, inspection images for process results can be transmitted via FTP communication, and inspection values ​​for process results can be transmitted via TCP / IP communication.

[0065] In the case of the conventional structure (300), since the standalone vision inspector (310) and the PC vision inspector (320) provide inspection data to the upper server (330) via the same communication method, data traffic may become excessively high. In particular, since all inspection images with relatively high capacity are transmitted via FTP communication, a situation may occur in which some data is lost due to traffic overload.

[0066] FIG. 4 illustrates communication methods for collecting inspection data according to some embodiments.

[0067] Referring to FIG. 4, a data management system (400) utilizing improved communication methods for collecting inspection data may be illustrated. The data management system (400) may correspond to the data management system (120).

[0068] Unlike the conventional structure (300), in the data management system (400), the PC vision inspector (420) can transmit inspection images and inspection values ​​to the collation device (430) using the SMB communication method. Therefore, since the standalone vision inspector (410) and the PC vision inspector (420) transmit inspection data using different communication methods, traffic overload can be prevented and data omission / loss can be prevented.

[0069] The inspection images transmitted by the standalone vision inspector (410) and the PC vision inspector (420) may both have a JPG data format. On the other hand, the inspection values ​​provided by the standalone vision inspector (410) may have a CSV data format, and the inspection values ​​provided by the PC vision inspector (420) may have a JSON data format. The data format of the inspection values ​​provided by the standalone vision inspector (410) may be converted from a CSV data format to a JSON data format by a collation device (430). The collation device (430) may execute software (Agent S / W) for data collation and management.

[0070] FIG. 5 illustrates a method of recording inspection data collected via communication methods according to some embodiments.

[0071] Referring to FIG. 5, a data management system (500) that manages test values ​​and test images as separate databases may be illustrated. The data management system (500) may correspond to the data management system (120).

[0072] In the data management system (500), the collation device (430) can transmit inspection value data and inspection image data to the management server (510). The management server (510) may be a server based on SPC+ (Serviced Privated Cloud Plus). The inspection value data may have a JSON data format, and the inspection image data may have a JPG data format.

[0073] The management server (510) can record inspection value data in a database (511) and inspection image data in a distributed file system (DFS, 512). The DFS (512) may refer to a data storage / management system that supports users or applications to access data files using a network. Since the inspection value data and inspection image data are managed in different ways, more efficient data management can be achieved.

[0074] Meanwhile, the process of providing inspection value data from the collation device (430) to the management server (510) may be performed based on MQTT (Message Queueing Telemetry Transport), AMQP (Advanced Message Queuing Protocol), and SOLACE. SOLACE may be a middleware platform that enables data to be moved in real time regardless of protocol, use case, pattern, location, or data type.

[0075] FIG. 6 illustrates steps of a data management method according to some embodiments.

[0076] Referring to FIG. 6, the data management method (600) may include steps (610) to (640). However, the present invention is not limited thereto, and some steps may be omitted or other general steps may be added, and the steps of the data management method (600) may be executed in a different order than the illustrated order.

[0077] The data management method (600) may be composed of steps that are processed in a time-series manner in the data management system (120). Therefore, even if the content is omitted below, the content described above for the data management system (120) may be equally applied to the data management method (600).

[0078] Steps (610) to (640) of the data management method (600) can be performed by the first inspection device (121), the second inspection device (122), the collation device (123), and the management server (124) of the data management system (120).

[0079] In step (610), the data management system (120) can generate a first inspection image and first inspection values ​​related to the result of the first manufacturing process of the battery cell through the first inspection device.

[0080] In step (620), the data management system (120) can generate a second inspection image and second inspection values ​​for the result of the second manufacturing process of the battery cell through the second inspection device.

[0081] In step (630), the data management system (120) can receive the first inspection image, the first inspection values, the second inspection image, and the second inspection values ​​using a plurality of communication methods through the collation device.

[0082] In step (640), the data management system (120) can record the first inspection image and the second inspection image in the first database and record the first inspection values ​​and the second inspection values ​​in the second database through the management server.

[0083] According to an embodiment, the data management method (600) may be implemented in the form of a computer program stored on a computer-readable storage medium. That is, the computer program may include instructions for implementing the data management method (600), and the program instructions may be stored on the computer-readable storage medium. The computer program may include a mobile application.

[0084] According to an embodiment, the computer-readable storage medium may include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical media such as CD-ROMs, DVDs, magneto-optical media such as floptical disks, and hardware devices specially configured to store and execute computer program instructions such as ROMs, RAMs, flash memories, and the like. The computer program instructions may include machine language codes generated by a compiler and high-level language codes that can be executed by a computer using an interpreter, etc.

[0085] The terms "include," "comprise," or "have" used herein, unless otherwise specifically stated, imply that the corresponding component may be included, and therefore should be interpreted to include other components rather than to exclude other components. All terms, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the embodiments disclosed in this document pertain, unless otherwise defined. Commonly used terms, such as terms defined in dictionaries, should be interpreted to be consistent with their contextual meaning in the relevant art, and shall not be interpreted in an idealized or overly formal sense, unless explicitly defined in this document.
